# 20230103 bkw: BUILD=3
# - use https URL for homepage in info file.
# - remove useless INSTALL from doc dir.

# 20210923 bkw: fix build on -current, mitigate buffer overflow.

# TODO: see if there's anything to these:
# https://www.cvedetails.com/cve/CVE-2007-1502/
# https://www.cvedetails.com/cve/CVE-2007-1503/
# ...these appear to be the same CVE. Huh.
# It looks autogenerated, and there's no POC. Pretty much all the
# buffer overflows would depend on the user typing >1024 characters.
# The patch below prevents that, at least. There are a bunch of
# format string warnings from gcc that deserve looking at, but I
# don't have the time right now.
